Over at Stennis NASA conducted a second RS-25 single engine hot fire test yesterday as part of a new series to support the development and production of engines for the agency’s Space Launch System (SLS) rocket on future missions to the Moon.
The full-duration hot fire of more than eight minutes (500 seconds) was conducted on the A-1 Test Stand at NASA’s Stennis Space Center.
NASA is building SLS as the world’s most powerful rocket. SLS will fly to the Moon as part of NASA’s Artemis program, including the Artemis I uncrewed test flight this year that will pave the way for future flights with astronauts to explore the lunar surface and prepare for missions to Mars. Four RS-25 engines help power SLS at launch, firing simultaneously to generate a combined 1.6 million pounds of thrust at launch and 2 million pounds of thrust during ascent.
